HARBOW.

Specification of Letters Patent.

atenten may 1a, 190e.

application and January' a, 190e. smal No. was* To all whom it mayconcern.'

Be it known that I, Lona F. `WnEnLnss,-a citizen of the United States,residing at' Vilonia, in the county of Faulkner and State of Arkansas,have invented certain new and useful Improvements in Harrows; and I dohereby declare the following to be a full', clear, and exact descri tionof the invention, such as will. enable ot ers skilled in the art towhich it appertains to make and use the same.

My invention relates to new and useful improvements in harrows, and moreparticularly to that class known as drag harrows and my object is toprovide means for adjustin'g the teeth of the harrow to various angles.

A further object is to provide means `for causing said teeth to dragover the surface of the soil or to dig into the same.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claims.

In the accom anying drawings which are made a part oi) this application,`Figure 1 is a perspective view of a harrow complete. Fig. 2 is asectional view thereof on an enlarged scale, showing the teeth extendingat an angle. Fig. 3 is a similar view, showing the teeth in a verticalposition, and, Fig. 4 is a similar view showing the teeth in position toenter the soil.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1 i'ndicates the crossbars of my improved harrow, said beams being secured together by'links 2and, if preferred, cach may e made in two sections and the right andleft sections secured together by means of latches 3 placed at themeeting ends of the sections.

Extending laterally across the bars 1, are beams 4, one end of saidbeams being secured to one of the cross bars by means of eye bolts5,'while the opposite ends of the beams arev provided with a pluralityof openin s 6, through which pass eye bolts 7, the o ject in providingthe plurality of openings 6, being to cause the teeth 8, carried by thecross bars, to travel at various angles.v

In securing the links between the cross bars 1, one end of the link issecured to an eye bolt 9 extending through the lower ed e of the crossbar, while the opposite end o the same link is secured to an eye bolt 10extending through the upper edge of the next succeeding cross and, if itis desired to give a shallow cultiva ilon to the soil, a double tree 11is secured te a set of eye bolts 10 at 'the upper edgev ci? the beam 1and the eye bolt 7 is placed 1n the opening 6 adjacent the outer ends ofthe beams 4, thereby separating the beams to the full extent of thelinks 2 and causing theteeth 8 and beams to which they are secured, torest at anangle, as best shown in Fig. Li, in which event the teeth willslide over the surface of the soil without entering the same to anygreat depth, thus adapting the harrow for surface cultivation inconnection with growing corn, or similar plants'. If, however, itisdesired to stir the soil and give a medium depth of cultivation, thebolts 7 are'engaged with the innermost opening 6 in the beams 4, whichwill result in disposing the teeth and beams carrying the same to avertical position, as shown in Fig. 3 ofthe drawnd, in this instance,the double tree 1l is secured to the opposite edge or' the harrow andtothe eye bolts 9 in. the lower edge of the beam 1, while, if desired togive'a deep and thorcugh cultivation to the soil, the eye bolts 7 areplaced in the middle o ening 6, thereby giving the teeth a slight orwardslant, so that said. teeth will readily enter the Seil when the harrowis operated in the manner shown in Fig. 4.

In conjunction with the barrow, a drag yfor leveling the soil may bereadily provided b attaching to the rear eye bolts, a bar 12am by makingsaid bar of sufficient weight, the surface of the soil will bethoroughly ulverized, as well as s moothed,so that the liiirrows made bthe teeth will be obliterated.

It wi l thus be seen that I have provided a very chea and economicalform of harrow and one wherein the teeth may be readily adjusted tocultivate the soil at various depths. It will further be seen that my imroved form of harrow may be very cheap y and, at the same time, stronglyconstA noted and,

'by securing the bar thereto, as shown, a drag will be provided forpulverizing the soil in the rear of the harrow.

What I claim is:

1. In a harrow of the class described, the combination with a pluralit fof cross bars, teeth on said cross bars, lin s between said cross bars,the yopposite ends of said links being secured to opposite edges of thecross bars; of beams extending across the cross bars, eye bolts ada tedto secure one end of thebeams to one o the cross bars, the oppo- Ahavinga series of openingsin one end, means to p1votally secure 4the oppositeends of the site ends of said beams having a series Vof oenings thereinandveye bolts carried by one o the cross ybars adapted to be disposed,re s ectively through said openings and adjust tiie teeth at various anles.

.2. The herein descri ed harroW, comprising the combination witha-plurality of cross bars, tee'th carried by said bars, links secured atone .end to the lower edge of one of the bars and the opposite end tothe upper edge of the next succeedinglbar, beams extending laterallyacross the cross bars, said' beams beams to 'one of the cross bars,additional 15,v

means carried by 'they-barst the opposite edge of the harrow adapted toenter said. openings and adjust the angle ofthe4 teeth and a double treeadapted to be secured at opPosite edges 'of the harrow.

n testimonyv whereof I have signed my name to this specification in thepresence of two subscribing Witnesses. l
